Bilharzia (Schistosomiasis)

Bill Harris from my reading and experience has to be the worst. Don't get too near the Nile!

Probably the worst for the sheer natstiness of how this disease works. Get this: the larvae enter through you skin, usually feet and start travelling through your tissue to your gut where they start laying eggs, thus making more larvae. The disease worsens as the larvae multiply and symptoms include a rash at entry site, extreme weakness, painful, bloody urination, hot flashes, loss of appetite and diarrhea. Once they reach your liver, you are very sick and susceptible to other illnesses like malaria or dysentery. If this ain't a reason to rip up your passport and head for Wisconsin Dells for your next vacation, I don't know what is.
